The image-generating device is switchable in two operating modes, the first operating mode being the standard operating mode for projecting, and the second being an operating mode in which the laser radiation is harmless to a person disposed in the region to which the laser has access. In this regard, a safety circuit is provided and comprises at least one sensor, by which a monitored region, which is larger than the region accessible to the laser, between the image-generating means and the projection screen is monitored as to the presence of objects, wherein the image-generating means is switchable into the second operating mode by means of the safety circuit, in the event of an object being present.
